DECK-PLATE.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed September 16, 1907. Serial No. 393,217.

T 0 all whom it may concern:

Be it known that I, ALBERT R. HURLBURT, a citizen of the United States,residing at Middletown, in the county of Middlesex and State ofConnecticut, have invented certain new and useful Im rovements in Deck-Plates, of which the 'ollowing is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to new and useful improvements in deck plates, andhas for its object, among other things, to provide a simple, convenientand economical locking means for securing the cover member.

To these, and other ends, my invention consists in the deck plate havingcertain details of construction, and combinations of parts, as will behereinafter described and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designatelike parts in the several figures; Figure 1 is a plan view of my deckplate complete; Fig. 2 is a view from the underside thereof; Fig. 3 is asectional view upon line A-B of Fig. 1; and Fig. 4 is a sectional planview of the bolt case upon line CD of Fig. 3 with the bolt therein.

In carrying out my invention I provide a body member 1 with anoverhanging flange 2 upon its top side, through which are the holes 3whereby the same is permanently secured,

and having an inwardly projecting lip 4 upon the interior thereof.

The cover member is designated by the numeral 5 and has a fixed hook 6thereon which projects under the lip 4, as shown in Fig. 3, anddiametrically opposite said fixed hook are the ears 7 between which ispivotally connected the latch 8 having a hook 9 upon one end andterminating at its other end in a finger piece 10 which lies in a recessin said cover member with the top surface thereof flush with the surfaceof said cover member when the hook end 9 is in engagement with theunderside of the hp 4, as shown in Fig. 3. A notch 11 is made in the topof the cover member 5 for convenience in grasping the finger piece 10when the same is in its down position.

Secured to the underside of the cover member, and substantially coaxialtherewith, is the bolt case 12 having a key pin 18 concentric therewith,and movably mounted therein is the locking bolt 14 having a notch 15 inone side thereof for the entrance of the key bit. Through the top of thecover member 5, and concealed beneath the finger piece 10, is the keyhole 16.

After the cover member is inserted within the body member the fingerpiece 10 is swung upon its pivot mounting so as to stand atsubstantially a right angle to the cover member, and while in thisposition the key is laced u on the pin 13 through the key hol e 16 anrotated in the bolt case, the bit of the key entering the notch 15 inthe bolt 14 and moving said bolt so that the end thereof is pushed underthe lip 4, after which the key is removed and the finger piece 10dropped into its closed position. l/Vhen the bolt is in the positionjust described it will be impossible to remove the cover member out ofthe body member without withdrawing the bolt, as the end thereof isunder the lip 4 upon one side and the fixed hook 6 upon the oppositeside of the center of said cover member.

There are minor changes and alterations that can be made within myinvention, and I would therefore have it understood that I do not limitmyself to the exact construction herein shown and described, but claimall that falls fairly within the spirit and scope of my invention.

What I claim as new and desire to secure I by Letters Patent, is

1. In a deck plate, the combination with the body member; of a covermember having fixed means thereon for securing said cover member u onone side thereof to said cover member; ocking means slidably mountedupon the underside of said cover member; and key means for actuatingsaid locking mechanism whereby said cover member will be secured to saidbody member.

2. In a deck plate, the combination with the body member; of a covermember; a latch member pivotally connected with said cover member havinglifting means upon one end thereof; a bolt connected with said covermember and lying substantially parallel therewith; and means forshifting said bolt, whereby said cover member is locked in said bodymember irrespective of the relative position of said cover member insaid body member.

3. In a deck plate, the combination with the body member; of a covermember; a latch member pivotally connected with said cover member havinglifting means upon one end thereof; and key actuated means for lockingsaid cover member in said body member, the key aperture of said meansbeing concealed beneath said lifting means when in one of its positions.

4. In a deck plate, the combination with the body member 1 having thelip 2 thereon; of the cover member 5 provided with the integral hook 6;the latch member 8 pivotally connected with said cover member; and thekey actuated bolt 14 movably connected with said cover member,substantially parallel therewith and upon one side of the centerthereof. I 5. In a deck late, the combination with the body mem er; of acover member; a latch member ivotally connected with said cover member laving lifting means upon one end thereof; a bolt connected with saidcover member and lying substantially parallel therewith; and means foractuating said bolt while said latch member is disengaged from said bodymember.

6. In a deck plate, the combination with the body member; of a covermember having a key aperture therethrough; and a latch member connectedwith said cover member and concealing said key aperture when in one ofits ositions.

7. n a deck plate, the combination with the body member; of a covermember; a notched locking bolt lying substantially parallel with saidcover member, actuated by key means from the outside of said covermember irrespective of the relative position of said cover member insaid body member; and a lifting means connected with said cover member,one end of which lies substantially flat with said cover member when inone of its positions.

In testimony whereof I afIiX my signature in presence of two witnesses.

ALBERT R. HURLBURT.
